beUI

Reach for beUI on top of shadcn/ui, not instead of it: it uses the same registry mechanism and the same Tailwind tokens (`shadcn init` first, then `bunx --bun shadcn add @beui/<name>`), and it fills the two gaps shadcn leaves — spring-driven interaction (morphing modal, dock, wheel picker, bottom sheet, pull-to-refresh) and AI agent chrome (prompt input, streaming response, tool result, approval card, file diff, citations). Verify a component exists before installing by hitting https://beui.dev/r/<name>.json, which returns proper registry-item JSON with its dependencies (usually just clsx and tailwind-merge). Two cautions: everything ships Motion and client-side state, so these are `use client` islands with real JS weight — keep them off static marketing pages — and the templates plus the richest blocks sit behind the $149 Pro paywall, so never import a Pro-only name into a free build.

Why it is here. It is one of the few registries covering agent-interface primitives (approval cards, tool results, streaming responses) with the same install ergonomics as shadcn/ui, which is exactly what an AI product build needs and shadcn does not ship.
